I try to be very careful about promoting generals. Aside from irking other generals that I might want to get promoted later, some of them have the innate characteristic of dropping in quality. Some examples are Hooker, Lyon, and Burnside.
So when Brigadier Grierson 5-2-3 (+1 defensive through experience)
got his letter of approval for promotion I checked the handy Union Generals list to see what his status is. it says he starts at 5-2-2, can be promoted to Maj. Gen. 5-2-2, but not higher. So I jumped at the opportunity.
But after his promotion he has dropped in quality anyway.
I thought that generals keep their experience gains when being promoted, baring changes due to being promoted above their abilities as in the examples above.
Is this normal?
